What Is Quality Assurance (QA)? A Complete Guide
Quality isn’t something you “add” at the end of a project – it’s something you design into every step. That’s where quality assurance (QA) comes in. In today’s competitive digital and manufacturing environments, QA plays a central role in building trust, reducing errors, and delivering consistent results.
This guide will explain what quality assurance is, how the process works, how it looks in actual business cycles (as well as the actual differences between quality control and quality assurance); common methods of quality assurance, how to conduct quality assurance; types of quality assurance by industry, and practical examples of quality assurance that can be put into practice.
Quality Assurance Meaning: What QA Actually Means
The quality assurance meaning refers to a systematic, proactive approach to ensuring that products or services meet defined quality standards. QA focuses on preventing defects by improving and controlling processes, rather than just finding problems after they happen.
The Strategy
ThinkAlternate deployed the Cloud Cost Optimizer module within MIRSA to:
- Audit AWS usage patterns, billing reports, and tagging inconsistencies
- Detect idle and over-provisioned compute/storage resources
- Simulate savings from instance rightsizing, auto-scaling adjustments, and storage tiering
- Optimize CI/CD workflows and serverless deployments to reduce runtime costs
- Deliver weekly savings reports with actionable remediations
Execution
- Connected AWS billing + usage APIs to MIRSA dashboards
- Identified 13 idle EC2 and 6 redundant RDS instances
- Enabled S3 Intelligent-Tiering and reduced snapshot frequency
- Shifted critical workflows to Lambda + API Gateway architecture
- Implemented MIRSA alerts for budget anomaly detection
Results
- Reduced monthly AWS spend from $11,800 to $4,950 (58% savings)
- 35% faster CI/CD deployments by optimizing build runners
- $72K annualized savings reinvested into growth campaigns
- Zero downtime across optimization rollout (100% availability)
